Outgoing Late Show host David Letterman, who will step down on May 20, will be the subject of a 90-minute primetime special celebrating his legendary career.

Spanning all the way back to his days as a weatherman in Indiana, the special will feature highlights from Letterman’s best interviews as well as his famous show segments such as the Top Ten List, Stupid Pet and Human Tricks. Some of his most poignant moments from behind the Late Show desk, like his first broadcast after the Sept. 11, 2011 terrorist attacks, will also be included.

David Letterman: A Life on Television will air May 4 at 9:30 p.m. on CBS.
